FIELD OF INVENTION

The present invention relates to new, distinct, and stable cultivars ofdouble-type Kalanchoe interspecific hybrids that produce one or moreflowers with at least 5 full or partial petals per flower. Thedouble-type Kalanchoe interspecific hybrids of the present inventioninclude Kalanchoe blossfeldiana x K. laciniata, K. blossfeldiana x K.rotundifolia, K. blossfeldiana x K. aromatica, K. blossfeldiana x K.pubescens, K. blossfeldiana x K. grandiflora, K. blossfeldiana x K.citrina, K. blossfeldiana x K. ambolensis, K. blossfeldiana x K.faustii, K. blossfeldiana x K. schumacherii, K. blossfeldiana x K.pritwitzii, K. blossfeldiana x K. flammea, K. blossfeldiana x K.figueredoi, K. blossfeldiana x K. rauhii, K. blossfeldiana x K. obtusa,K. blossfeldiana x K. pumila, K. blossfeldiana x K. marmorata, K.blossfeldiana x K. porphyrocalux, K. blossfeldiana x K. jongmansii, K.blossfeldiana x K. pinnata, K. blossfeldiana x K. diagremontiana, K.blossfeldiana x K. gracilipes, K. blossfeldiana x K. campanulata, K.blossfeldiana x K. latisepela, K. blossfeldiana x K. coccinea, K.blossfeldiana x K. fedtschenkoi, K. blossfeldiana x K. tubiflora, K.blossfeldiana x K. decumbens, K. blossfeldiana x K. manginii, K.blossfeldiana x K. orgyalis, K. blossfeldiana x K. crenata and K.blossfeldiana x K. tomentosa. The double-type Kalanchoe interspecifichybrids of the present invention also include double-type plantsproduced from crosses between the above-identified interspecific hybrids(e.g. (K. blossfeldiana x K. laciniata) x (K. blossfeldiana x K.pubescens)), as well as, crosses between interspecific hybridscontaining K. blossfeldiana and interspecific hybrids not containing K.blossfeldiana in the genetic background (e.g. (K. blossfeldiana x K.laciniata) x (K. grandiflora x K. pritwitzii)). The double-typeinterspecific hybrid plants produce one or more flowers having at least5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23,24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, ormore than 40 petals per flower. The double-type characteristic has beensuccessfully introgressed from double-type K. blossfeldiana into othersingle-type (4 petals per flower) Kalanchoe species. The double-typeinterspecific hybrid plants can be used as either male or female parentsin crosses to the parents, other selections from the same species as theparents, or selections from other Kalanchoe species. The double-typeinterspecific hybrid plants can also be selfed. The double-typeflowering characteristic from K. blossfeldiana has been combined withmany desirable traits from other Kalanchoe species including differentflower colors, superior growth characteristics and improved plant habit.Methods for the reliable breeding of the double-type characteristic fromK. blossfeldiana, or Kalanchoe interspecific hybrid plants, into diversesingle-type Kalanchoe genetic backgrounds, as well as methods forincreasing the number of petals per flower, are disclosed.

BACKGROUND OF THE INVENTION

The present invention relates generally to the field of ornamentalKalanchoe plants. The genus of Kalanchoe belongs to the sedum family(Crassulaceae). There are more than 100 different species of Kalanchoeof which more than 60 are found in Madagascar. Many species are found inSouth Africa and a few in Asia and South America. Kalanchoe belongs tothe succulent plant group, which are characterized by their turgidleaves. The leaves enable members of this genus to survive droughtconditions. Consequently, Kalanchoe are useful ornamental plants becausethey can survive in less than optimal growing conditions.

Species of Kalanchoe are described in J. T. Baldwin, Amer. J. Bot. 25:572-579 (1938). Each species of Kalanchoe has traits a breeder wouldlike to incorporate into commercial cultivars. Other traits a breederwill try to avoid.

K. blossfeldiana is a valuable ornamental species because it can bereadily grown from seed, or reproduced asexually from cuttings, andproduces abundant flowers that remain fresh for several weeks.Generally, K. blossfeldiana plants are highly branched and under certainconditions the height of the branches may be up to 30-45 cm. K.blossfeldiana plants generally produce erect flowers, oblong orovate-oblong leaves, with a corolla that is red.

K. blossfeldiana can be crossed with numerous other Kalanchoe species tocombine advantageous characteristics into unique new cultivars. Amongthe numerous interspecific hybrids that may be created are K.blossfeldiana x K. laciniata, K. blossfeldiana x K. rotundifolia, K.blossfeldiana x K. aromatica, K. blossfeldiana x K. pubescens, K.blossfeldiana x K. grandiflora, K. blossfeldiana x K. citrina, K.blossfeldiana x K. ambolensis, K. blossfeldiana x K. faustii, K.blossfeldiana x K. schumacherii, K. blossfeldiana x K. pritwitzii, K.blossfeldiana x K. flammea, K. blossfeldiana x K. figueredoi, K.blossfeldiana x K. rauhii, K. blossfeldiana x K. obtusa, K.blossfeldiana x K. pumila, K. blossfeldiana x K. marmorata, K.blossfeldiana x K. porphyrocalux, K. blossfeldiana x K. jongmansii, K.blossfeldiana x K. pinnata, K. blossfeldiana x K. diagremontiana, K.blossfeldiana x K. gracilipes, K. blossfeldiana x K. campanulata, K.blossfeldiana x K. latisepela, K. blossfeldiana x K. coccinea, K.blossfeldiana x K. fedtschenkoi, K. blossfeldiana x K. tubiflora, K.blossfeldiana x K. decumbens, K. blossfeldiana x K. manginii, K.blossfeldiana x K. orgyalis, K. blossfeldiana x K. crenata and K.blossfeldiana x K. tomentosa.

The breeding of Kalanchoe interspecific hybrids with double-type,rose-like flowers, with more than 5 petals per flower, offers a uniqueflower form that can be combined with diverse Kalanchoe plantcharacteristics from different species, thereby expanding the range ofphenotypic characteristics available in this popular horticulturalplant.

DETAILED DESCRIPTION

As used herein, “single”, or “single-flowering”, or “single-type” areeach defined as the typical Kalanchoe plant which produces flowershaving 4 petals per flower.

As used herein, “double”, “double-flowering”, or “double-type” are eachdefined as a Kalanchoe interspecific hybrid plant which produces one ormore flowers having at least 5 full or partial petals per flower.Preferably, the double-type Kalanchoe interspecific hybrid plant of theinstant invention has substantially all double-type flowers. Thedouble-type flowers of the instant invention have about 6, 7, 8, 9, 10,11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28,29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, or more than 40 petalsper flower. A double-type Kalanchoe interspecific hybrid plant of theinstant invention may produce flowers with a relatively uniform numberof petals per flower and this characteristic is stable through asexualreproduction. Alternatively, a double-type Kalanchoe interspecifichybrid plant of the instant invention may produce flowers with a widerange in the number of petals per flower and this characteristic is alsostable through asexual reproduction.

As used herein, the “degree of doubleness per flower” is defined as ameasure of the number of extra full or partial petals per flowerproduced beyond the number 4 normally found on Kalanchoe single-typeplant. The greater the degree of doubleness per flower, the greater thenumber of full or partial petals produced per flower.

As used herein “the degree of doubleness per plant” is defined as ameasure of the number of flowers per plant, which have at least 5 petalsper flower. The greater the degree of doubleness per plant, the higheris the percentage of total flowers produced by the plant which have atleast 5 full or partial petals per flower.

As used herein, “interspecific hybrid” includes the progeny from thecross of two different species of Kalanchoe, as well as progenyresulting from subsequent backcrossing to one of the parents. Thisbackcrossing to one of the parents may be conducted one or more timeswith the goal of stably combining the double-type trait with desiredcharacteristics.

K. blossfeldiana can be crossed with numerous other Kalanchoe species tocombine advantageous characteristics into unique new cultivars. Amongthe numerous interspecific hybrids that may be created are K.blossfeldiana x K. laciniata, K. blossfeldiana x K. rotundifolia, K.blossfeldiana x K. aromatica, K. blossfeldiana x K. pubescens, K.blossfeldiana x K. grandiflora, K. blossfeldiana x K. citrina, K.blossfeldiana x K. ambolensis, K. blossfeldiana x K. faustii, K.blossfeldiana x K. schumacherii, K. blossfeldiana x K. pritwitzii, K.blossfeldiana x K. flammea, K. blossfeldiana x K. figueredoi, K.blossfeldiana x K. rauhii, K. blossfeldiana x K. obtusa, K.blossfeldiana x K. pumila, K. blossfeldiana x K. marmorata, K.blossfeldiana x K. porphyrocalux, K. blossfeldiana x K. jongmansii, K.blossfeldiana x K. pinnata, K. blossfeldiana x K. diagremontiana, K.blossfeldiana x K. gracilipes, K. blossfeldiana x K. campanulata, K.blossfeldiana x K. latisepela, K. blossfeldiana x K. coccinea, K.blossfeldiana x K. fedtschenkoi, K. blossfeldiana x K. tubiflora, K.blossfeldiana x K. decumbens, K. blossfeldiana x K. manginii, K.blossfeldiana x K. orgyalis, K. blossfeldiana x K. crenata and K.blossfeldiana x K. tomentosa.

K. decumbens, K. manginii, K. orgyalis, K. crenata, K. tomentosa, K.rauhii, K. obtusa, K. latisepela and K. tubiflora are Kalanchoe specieswhich can be crossed with any of the other Kalanchoe species disclosedin this specification to yield new Kalanchoe hybrids expressing new andunique phenotypes when compared to the Kalanchoe culture in general. Forexample, some of the new and unique phenotypes that may be expressed,include but are not limited to, larger flowers, bell-type flowers,unique flower color combination, smaller or larger leaves, change ofleaf shape, and different growth habits, such as height, spread andvigor of Kalanchoe hybrid.

K. blossfeldiana x K. laciniata interspecific hybrids typically haveleaves that are entire, sinuate or parted with erect and large flowersthat are white, pink, purple, yellow, orange, and red. K. blossfeldianax K. laciniata interspecific hybrids are highly branched, relativelycompact and under certain conditions the height of the branches may beup to 30-45 cm.

K. blossfeldiana x K. rotundifolia interspecific hybrids typically haveorbicular and elliptic leaves and relatively small flowers. K.blossfeldiana x K. rotundifolia interspecific hybrids are upright andhave a uniform growth habit, and under certain conditions, the height ofthe branches may be up to 35 cm.

K. blossfeldiana x K. aromatica interspecific hybrids typically havemedium sized flowers and orbicular shaped leaves, with a tendency ofbending downwards. K. blossfeldiana x K. aromatica interspecific hybridsare upright and have a uniform growth habit, and under certainconditions, the height of the branches may be up to 18 cm.

(K. blossfeldiana x K. laciniata) x. (K blossfeldiana x. K. pubescens)double type interspecific hybrids typically have ovate, as well as,hastate leaves. (K. blossfeldiana x K. laciniata) x. (K. blossfeldianax. K. pubescens) interspecific hybrids are upright and have s uniformgrowth habit, and under certain conditions, the height of the branchesmay be up to 26 cm.

Double-type Kalanchoe interspecific hybrid cultivars are geneticallystable, as evidenced by the stability of the double-type trait throughboth asexual propagation and sexual crosses. The data from numerouscrosses with K. blossfeldiana indicate that the double-type traitsegregates as a single dominant gene. The double-type trait can bereproducibly and predictably introgressed into diverse Kalanchoe speciesand genetic backgrounds.

K. blossfeldiana seeds designated ‘MP African’ that produce plantscarrying the double-type gene or trait, and which can be used as a maleor female parent in crosses with Kalanchoe species to producedouble-type Kalanchoe interspecific hybrid cultivars, were deposited onDec. 9, 2004 at the American Type Culture Collection (ATCC), P.O. Box1549, Manassas, Va. 20108, U.S.A., and accorded ATCC accession no.PTA-7896.

As a first step in making interspecific hybrids of the instantinvention, a single or double-type Kalanchoe plant selection is crossedwith a single-type Kalanchoe selection from another species. Progeny arescreened for fertile selections. Large numbers of progeny may have to bescreened to identify fertile selections. The fertile selections may bescreened for those exhibiting the double-type flower trait if one of theparents was a double-type selection. Alternatively, the single-typefertile interspecific hybrid is crossed, either as the male or femaleparent, with a double-type Kalanchoe selection. A double-type hybridprogeny plant with desirable phenotypic characteristics is propagatedasexually by conventional methods to determine if the phenotypiccharacteristics are stable.

For example, a K. blossfeldiana (tetraploid) x K. laciniata (diploid)interspecific hybrid is by nature triploid and thus sterile. K.blossfeldiana x K. laciniata interspecific hybrid progeny plants werescreened and ‘Yellow African’, described in U.S. Plant Patent No.12,299, was identified. This fertile K. blossfeldiana x K. laciniatainterspecific hybrid has been used to breed a series of interspecifichybrid cultivars designated African Treasures™. One such cultivar wasdesignated ‘KJ 2000 0716’ and is described in pending U.S. plant patentapplication Ser. No. 10/654,571, incorporated herein by reference.

‘KJ 2000 0716’ was identified in the progeny originating from a crossbetween ‘Yellow African’ and a single-type K. blossfeldiana. The threenew double-flowered Kalanchoe interspecific hybrids described inExamples 2, 3 and 4 herein originated from crosses between ‘KJ 20000716’ as the female parent, and ‘Monroe’ as male double-type K.blossfeldiana parent. ‘Monroe’ is described in U.S. Plant Patent No.14,714.

Recurrent selection is used to increase the number of petals per flowerfound in the Kalanchoe interspecific hybrid plants of the instantinvention. A double-type Kalanchoe interspecific hybrid plant is selfed,or crossed to another double-type Kalanchoe plant, and the progenyscreened for plants with double-type flowers with an increased number ofpetals per flower compared to the double-type parents.

1. General Breeding Methods

The Kalanchoe plants of the instant invention were crossed as follows.When the pistil is fully developed and the anthers have not opened, thepistil is to some extent uncovered. During this time the stigma issusceptible to pollination. Pollen is harvested from the male using apencil or small brush and transferred to the stigma. Once pollination iscomplete, the seeds develop within the ovary and the pistils areharvested when ripe. The seeds are dried before sowing in peat-basedsoil mix.

Breeding with double-type K. blossfeldiana requires careful uncoveringof the pistil. It is very easy to wound the ovary and thereby hindergermination and development of seeds. In addition, if the female parentis water-stressed during pollination and subsequent seed development,the number of seeds obtained appear to increase.

2. Plant Growth Conditions

The Kalanchoe plants described herein were grown in a greenhouse at64.4° F. during the day and 68° F. during the night. The plants wereproduced in pots with a diameter of 10.5 cm or 13 cm. Cuttings weregrown under long-day conditions (16 hours light, 8 hours night) duringthe first 3-8 weeks following planting, depending on cultivar and potsize. Between 4-9 weeks after planting, the plants were transferred toshort-day conditions (10 hour light and 14 hour dark). The flowering isinduced by short-day conditions. Between 13-19 weeks after planting,depending on cultivar, pot size, and time of year, the plants weremature with flowers that were opening or about to open.

The plants were grown under natural light conditions supplemented with70 μmol/m2/s SON-T light when the natural light was less than 100μmol/m2/s. Plants were grown in a peat based soil mix and were wateredwith a solution containing 200 parts per million (ppm) nitrogen, 200 ppmpotassium, 40 ppm phosphorous, 200 ppm calcium, 40 ppm magnesium, 60 ppmsulphate, 1 ppm iron, 0.6 ppm manganese, 0.1 ppm copper, 0.1 ppm zinc,0.3 ppm borium, 0.03 ppm molybdenum.

The following examples are set forth as representative of the specificand preferred embodiments of the present invention. These examples arenot to be construed as limiting the scope of the invention in anymanner. It should be understood that many variations and modificationscan be made while remaining within the spirit and scope of theinvention.

EXAMPLE 1

The data from numerous crosses with K. blossfeldiana indicate that thedouble-type trait segregates as a single dominant gene. A total of 9,787progeny from crosses of K. blossfeldiana double-type x K. blossfeldianasingle-type have been analyzed. Among these 9,787 progeny, 2,956exhibited the double-type trait. Seeds carrying the double-type traitgerminate at a lower frequency than seeds carrying the single-typetrait. This lower germination frequency has probably impacted thesegregation pattern which is not the 1:1 ratio expected for a traitcontrolled by a single dominant gene. Regardless of what the geneticbasis for control of the double-type trait in Kalanchoe might be, thesedata demonstrate the double-type trait can be reproducibly andpredictably introgressed into diverse Kalanchoe genetic backgrounds.

EXAMPLE 2 Cultivar ‘KJ 2003 0761’

The new K. blossfeldiana x K. laciniata interspecific hybrid ‘KJ 20030761’ was produced using a proprietary single-type selection of K.blossfeldiana x K. laciniata designated ‘KJ 2000 0716’, as the femaleparent. This female parent is described in pending U.S. plant patentapplication Ser. No. 10/654,571 and in European Union Community VarietyRights application serial No. 2003/0974, and is the second generationprogeny of a fertile interspecific hybrid between K. blossfeldiana andK. laciniata. The male parent was a K. blossfeldiana double-typeselection designated ‘Monroe’, and is described in U.S. Plant Patent No.PP 14,714. The new Kalanchoe cultivar ‘KJ 2003 0761’ was discovered andselected as a flowering plant within the progeny of the stated cross ina controlled environment in Hinnerup, Denmark.

Asexual reproduction of the new cultivar by vegetative terminal cuttingswas first performed in February, 2004, in Hinnerup, Denmark, and hasdemonstrated that the combination of characteristics as herein disclosedfor the new cultivar are firmly fixed and retained through successivegenerations of asexual reproduction. The new cultivar reproducestrue-to-type through asexual reproduction.

The female parent is described in pending 1) U.S. Plant patentapplication Ser. No. 11/011,611, 2) European Union Community VarietyRights Application No. 2004/0546, and 3) Canadian Plant Breeder's RightsApplication No. 05-4713, and is a fertile interspecific hybrid betweenK. blossfeldiana and K. laciniata. The male parent was a fertile hybridbetween K. blossfeldiana and K. pubescens. The new Kalanchoe cultivar‘KJ 2005 0159’ was discovered and selected as a single flowering plantwithin the progeny of the stated cross in a controlled environment inHinnerup, Denmark.

The new interspecific hybrid is here described by a flowering seedlingof ‘KJ 2005 0159’.

Asexual reproduction of the new cultivar by vegetative terminal cuttingshas not been performed to date.

The following traits have been observed and are determined to be uniquecharacteristics of the new Kalanchoe cultivar ‘KJ 2005 0159’ which incombination distinguish this Kalanchoe as a new and distinct cultivar:

-   -   1. a large number of petals per flower resulting in a        double-type or multi-petalled trait;    -   2. the medium size of petals resulting in a medium diameter        flower;    -   3. small, dissected leaves on young, as well as, mature leaves;    -   4. the orange-red colored petals; and    -   5. a large number of flowers per plant.

The new Kalanchoe cultivar ‘KJ 2005 0159’ has not been observed underall possible environmental conditions. The phenotype of the new cultivarmay vary significantly with variations in environment such astemperature, light intensity, and day length without any change in thegenotype of the plant. The following observations, measurements andvalues describe the new Kalanchoe cultivar ‘KJ 2005 0159’ as grown inHinnerup, Denmark, under conditions which closely approximate thosegenerally used in commercial practice.
